A drain II] in the sink bowl l is connected to waste pipe I I.

In the drainboard 2 is a circular opening which set portion about thetub opening providing a narrow circular flange I6 which supports aradially outwardly directed flange 11 formed about the upper edge of thetub side wall 12. A sealing gasket [8 of rubber or cork is interposedbetween the flanges l6 and f1.

In the tub bottom I is a drain opening 19 which is connected by aconduit 20 to a T 2| 1n A shut-off valve 22 is proso that washing liquidthe washer tub or the waste pipe ll. vided in the conduit 20 may beeither retained in drained therefrom as desired.

The power unit for actuatirig'the washer is in the form of an integralassembly mounted on the tub bottom and comprises a housing structure 24that is secured in place by screws 25 that extend through the tub bottom15 and are threaded into bosses formed in top wall 26 of the housing. Anintegral guide sleeve or journal 21 is formed at one end of the top wall26 of the housing and extends upwardly through an opening in the bottom[5 of the tub. Through the opening in the guide sleeve 21 extends a.drive assembly comprising an outer tubular quill 28 and an inner shaft29, the shaft being rotatable in the quill and guided in bushings 30 and3|. A flanged bushing 32 is interposed between the quill 28 and theguide sleeve 21.

The shaft 29 is longer than the quill 28 and extends through both endsof the latter, the lower end of the shaft continuing through the chamberin the housing, through a guide sleeve 34 in a cover 35 attached tohousing bottom 36 and terminating in a coupling 31 which drivinglyconnects the shaft to shaft 38 of an electric drive motor 39. The motoris disposed with the shaft 38 vertical and is attached to the housingcover 35 by screws 40. Thus the motor 39, shaft 29, quill 28, and guidesleeve 21 are in coaxial relationship for rotative movement of the shaftand quill about a common vertical axis. A seal 4| surrounds the lowerend of the shaft 29 and is received in a recess-formed in the lower endof the guide 34, to prevent loss of lubricant along the shaft out of thehousing 24. r

A bevel gear 43 is secured on the shaft 29 by a pin 44 and bears onthe'upper end of the guide sleeve 34 to support the shaft. A sleeve 45surrounding the shaft 29 bears on the upper end of the gear 43 and isformed at its upper end with a circular flange that engages a radialflange formed on the lower end of the bushing 3|, thus serving as asupport for the quill 28. An intermediate drive shaft 46 is supportedhorizontally for rotation within the housing 24, being journalled inintegral bosses or bracket elements 41 and 43 extending into the housingchamber from the housing walls. A bevel gear 49 meshing with the bevelgear 43 is secured by a pin 56 on that end of-the shaft 46 which isadjacent the vertical shaft 29. A worm 52 is secured on the other end ofthe intermediate shaft 46 by a pin 53 and meshes with a worm gear 54secured adjacent the lower end of a reduced diameter portion 55 of avertical driven shaft 56. The shaft 56 is disposed outside the tub walll2 and extends downwardly through a grease seal 41 received in acircular recess formed on the outside of a boss in the top wall 26 ofthe housing. A circular shoulder 58 at the juncture of the reduceddiameter portion 55 and the full diameter portion of the shaft 56 bearson a washer 59 that seats in the grease sealrecess and supports theshaft and the parts carried by the latter.

Rotation of the worm 52 turns the worm gear 54 and the shaft 56 atrelatively low rotational speed, the shaft 46 being driven atapproximately the same rotational speed as the impeller drive shaft 29by the bevel gears 43 and 49 which are of approximately the same size.

On the lower end of the reduced diameter shaft portion 55 is secured acrank 60 which carries one end of a connecting rod 6|. The other end ofthe rod is received on a pin in an arm 62 formed as an integral radialextension on the lower end of the quill 28. The arm 62 includes a flangeportion 63 which underlies the guide sleeve 21 of the housing and limitsupward movement of the quill in the sleeve. The crank 60 is of lesslength and throw than the quill arm 62 so that as the shaft'portion 55is rotated, the rod 6| is moved back and forth by the circular movementof the crank 66 oscillating the arm 62 over an arcuate path of about toabout or more, but less than and thereby imparting reciprocatingrotative movement to the quill 26. Such rotative movements of the quillwhile occurring in simultaneous timed relation to the rotary movement tothe shaft 29, are at a relatively slower rate of speed than that of theshaft. By reason of the speed reduction effected through the form 52 andworm gear 53 the torque imparted to the quill 28 is higher than that ofthe shaft 29.

The end of the intermediate shaft 46 extends through a partition 65inside the housing and drives a small spur gear 66 mounted on the shaft.A larger gear 61 secured on a short shaft 68 meshes with the spur gear66 and is driven by the latter at a relatively slower rotational speed.The shaft 68 is journaled in an elongated boss 69 formed in an end coverplate 10 of the housing 24. The inner end of the short shaft 69 isguided in a journal boss formed in the partition 65. Outer end 12 of theshaft 68 is formed square or non-circular in shape to receive and drivea coupling of a flexible power transmission shaft assembly, not shown.Such coupling may be held in place as by a collar screwed onto threads13 formed on the outer end of the journal boss 69. Thus a power take-offis provided for turning a. flexible shaft assembly at an intermediaterotative speed, slower than the shaft 29 and faster than the oscillatorymovements of the quill 28 and the shaft 56 which, as will later appear,drives the wringer.

. Clothes washing When the washer is to be used for the purpose ofwashing clothing and other fabric materials an agitator A is placed inthe tub and mounted on the dual drive column. The agitator comprises acentral post 14 the lower portion of which is hollow and receives thequill 26. The upper end of the quill is of hexagonal or othernon-circular shape as indicated at 15 and has interfitting drivingconnection in a similarly shaped socket formed interiorly of the post soas to establish a driving connection between the quill and the agitator.

Adjacent the upper end of the guide sleeve 21 and the quill 2,8 isformed with .a circular sectioned guide portion 16 that is-slidinglyreceived in the lower end of the agitator post 14 to locate andstabilize the agitator in the tub and prevent lateral swaying andtwisting of the agitator in use. A wide circular flange H is formedintegrally on the bottom of the agitator post M and a number of uprightvanes or wings T8 are disposed in the angle between the agitator post 14and the flange TI. The agitator may be cast integrally of light materialsuch as aluminum or of a plastic material such as a phenol formaldehyderesin.

The chamber within the agitator post Hi is extended upwardly beyond thesocket portion which receives the hex-end E of the quill to provide aclearance chamber 80 which receives upper-end 8| of the impeller driveshaft 29. The shaft end 8| is square or of other non-circular section soas to be capable of establishing a driving connection with the impelleras will later appear. Since'the shaft rotates at a relatively high speedwhile the quill oscillates at a relatively low speed, it is es-. sentialthat the shaft turn freely in the agitator. Accordingly, the chamber 80is made of suificient sizev to provide clearance between the agitatorpost and the shaft end B I.

A water soap solution or other washing liquid is introduced into the tubapproximately to the level indicated at 82 the valve 22 being closed andthe motor 39 is energized from a suitable source of electric currentthrough a switch 83 which may be mounted on splashboard 4 of the sinkstructure. Clothing and other similar items to be washed are placed inthe liquid in the tub and subjected to the washing action of the liquidwhich is moved first in one direction and then reversed by thereciprocating movements of the agitator A. A cover 84 is placed over thetub to prevent escape of washing liquid. When the washer is not in usethis cover, being flat, serves as a work table or counter. The washingaction of the present machine when operating with the agitator A isquite similar to that of conventional type agitator washing machines.

A wringer 85 of conventional construction and having the usual rubbercovered rolls 86 and 81 is formed at one end with a depending hollowsupporting post 88 which has a reduced diameter or plug end portion89receivable within a cylindrical socket formed in a cup 90 mounted in thedrainboard of the sink. The cup journals the upper end of the verticalshaft 56 and has an outwardly directed radial flange 9! around its top,this flange being supported on a downwardly offset circularflange 82formed in the drainboard 2.

A sealing gasket 93 is disposed between the cup flange BI and thesupporting flange 92 and the parts are drawn and held together by athreaded collar 94 received on a threaded portion of the cup. A numberof integral radial ribs 95 are formed in the bottom of the cup 90 andare engaged in mating notches formed in the lower end of the reduceddiameter portion 89 of the wringer post 83. The interengagement betweenthe ribs 95 of the cup and the mating notches of the wringer post holdthe wringer assembly in predetermined rotative positions and preventbodily turning of the wringer with respect to the drain board. Thus thewringer is supported cantilever fashion on the post 88 and can-be swungto and retained in any desired operation position, or the wringer may beremoved bodily from the socket to clear the drainboard for other uses.

The wringer rolls 86 and 81 are driven through suitable mechanisms, notshown, by a shaft 96 thelower end ofwhich is, guided in abushing 91held, by a pressfitin an axial bore formed in reduced diameter or plugendportion 89 of the wringer column. The lower end of the wringer shaft96 abuts and drivingly interfits with the upper end of the verticalshaft 56, a diametrical key 98 being formed on the latter andinterfitting in a corresponding diametric slot in the shaft 96 toestablish the driving connection between the shafts. In this manner thewringer rolls 86 and 8"! are driven by themotor 39.

When the wringer is not. in use the'plug end 89 of the wringer post islifted out of the socket of the cup 9i! and the wringer is storedelsewhere. In such case the socket is closed by a suitable threadedcover, notshown, threads being provided in the upper end of the socketfor this pur-. pose.

Dish washing The machine of the present invention can be usedalternatively as either a clothes washer or a dish washer. To convert'to dish washing the agitator A is removed and replaced by an impeller I(Fig. 5). This'impeller which may be made by casting of a suitable lightmetal or plastic comprises a circular sectioned hollow hub Hit which isreceived over the drive column and is supported on the upper square end8| of the shaft 29. A matching socket is provided in the upper end ofthe hub chamber to receive the square end 8| of the drive shaft 23 sothat the impeller is actuated by the latter to turn at high rotationalspeed such, for example; as about 800 to about 1800 P. M., the latterbeing preferable. The hollow interior of the impeller hub H19 includes achamber portionllll sufiiciently large to accommodate and provide aclearance around the hexagonal drive end 75 of the quill 28 so that theimpeller be rotated relative to the quill.

Adjacent the lower end of the impeller the walls of the internal hubchamber are formed to closely surround the cylindrical guide portion 76of the quill 28 so that the impeller although turning relative to thequill is guided by the latter. A metal insert bushing I02 may be cast inplace in the impeller to rotate on the quill guide 15.

A pair of helical scoopsor vanes I 84 extend radially out from oppositesides of the impeller hublllli. Each of the scoops [M is of trough-likeform and at the bottom of the. hub terminates in a substantiallystraight radially extending bottom edge H15 which is disposed closelyadjacent the surface of the tub bottom 15. The impeller vanes Hi4maycarry integral concentric partition walls 563 which form open toppedchannels I [3 closed at their upper ends. At high rotational speeds theimpeller I, rotating so as to advance the radial edges H35 ofthe scoopsinto the washing liquid in the tub picks up such liquid and raises italong the scoops I84 and throws it radially outward over dishes andother articles being washed. Radial holes 523, in the vanes HM releasethe washing liquid from the impeller scoops. For

,. dishwashing purposes a smaller quantity of washing fluid is used thanfor washing clothing. For example, the washing liquid, which may be asoap solution or a water solution of any other conventional detergent,is placed in the tub up to about the level indicated at I96 (Fig.5).

Dish basket To support the dishes and otherhardware items being washed aremovable-basket structure B is placed inlthetub over theimpellerl. Thisbasket is composed of wire'or rod elements that are preferably stainlesssteel or other non-rusting metal or they may be plated metal if desired.A number of peripheral rod uprights I01 are held in spaced generallyparallel relation to one another by top hoop I08, intermediate hoop I09and bottom hoop I I to the outside of which the uprights areindividually welded or soldered. The bottom ends of the uprights I0'I,or some of them, are curved inwardly corresponding to the contour of thetub and form supporting feet II2 of the basket. Lengths of rubber tubingI I I are frictionally received on the basket feet I I2 and serve ascushions to contact the surface of the tub bottom I5.

The upper ends of the uprights I0'I, or some of them, are curvedinwardly and downwardly over the top hoop I08 providing angularlydisposed guide portions H4. The ends of the guide portions II4 on thetops of the upright rods terminate in inwardly directed radial portionsII5 which are welded or soldered to the underside of an inner hoop II6of less diameter than the top hoop I08.

Within the basket B provision is made for supporting a number of dishesin several similar groups. Fig. 7, showing the plan of the basket,illustrates a novel scheme for accommodating 5 groups of dishes eachcomprising a series of plates of decreasing sizes. Large plate P-I ofeach group is disposed obliquely across the tub and basket ahead ofintermediate plate P-2, the latter being ahead of small plate P-3. Thedishes are all supported in generally upright positions, the dishes ofeach group being one behind another and the several groups beinggenerally radially disposed about the impeller I or central source ofthe cleansing spray. In each group, the several dishes are located atdiiferent distances from the spray source or impeller. For example, theintermediate dish P-2 is further away from the source than the largedish P-I and the small dish P-3 is further still from the source of thespray liquid. This arrangement positions the relatively large or dinnerplate which is apt to be the most soiled and the hardest to cleanse,relatively close to the spray source while the other plates which may bethe salad and butter plates are relatively further away from the spraysource.

It is also to be noted that the plane of each dish, which may be takenas the plane of the dish periphery, is disposed at an acute angle to theplanes of the other dishes of the same group. This non-parallelarrangement improves the washing action and promotes the break-up anddistribution of the cleansing spray as released from the impeller. Alsoit is to be noted that each of the dishes faces generally in anon-radial direction with respect to the center of the tub and basket.

To support the dishes in the positions shown a number of wire or rodelements are supported in the basket by cross bars I I1 and I I8. Thecross bars Ill extend from the bottom hoop III] in a generally radialdirection to a center hoop II9 to which they are welded or soldered. Thecross bars II8 extend from the bottom hoop IIO to which they are securedto an adjacent cross bar III to which they are also secured. The crossbars Ill and H8 are arranged in pairs, one pair for each group of.dishes to be supported in the basket. The bars of each pair aresomewhat divergent to'accommodate the different sizes of dishes, theedges of which fit down between the cross bars. The more widely spacedparts of the cross bars are adjacent to the large dishes corre-'sponding to the dish P-I.

Between the cross bars are arches formed of bent wires or rods havingdivergent side elements I20 and I2I and top cross elements I22. The endsof the side elements of each arch are secured to the cross bars II I andH8 so that the arches extend upwardly from the cross bars to engage thebottoms of the plates which are propped against the arches and areinclined backwardly a few degrees so that water impinging against theupper portion of the plates flows downwardly by gravity over the platesurface'in a cleansing action.

Above the impeller I a wire mesh basket I24 is supported by upright barsI25, the lower portions of which are divergent to clear the impeller andthe bottom ends of which are secured to the small hoop II9. Hoops I26and I2'I support and surround the basket I24 to protect the latter andare secured to the uprights I25. Cutlery and small items to be washedare placed in the basket I24 and receive the liquid spray directly fromthe top of the impeller I.

Cups, small saucers and the like are disposed on a tray structurecomprising an outer hoop I28 and inner hoops I29 and I30. A number ofradial bars or rods I3I are secured at their outer ends to the largehoop of the tray structure and have inner ends which are bent to providevertical uprights I32 which are secured to the insides of the hoops I29and I30. The interior of the tray structure is thus clear so thatcutlery in the basket I24 may extend upwardly through the hoops I29 andI30. The tray hoop I28 is of less diameter than the top hoop II8 of thebasket while being of greater diameter than the small hoop IIB carriedby the guide portions II4 of the basket uprights. Thus the traystructure may be supported on the guide portions I I4 of the basketuprights, the tray hoop II8 interlocking or embracing the basket hoopII6 to prevent lateral displacement and tipping of the tray.

During operation as a dishwater the liquid is picked up from the bottomof the tub by the impeller I and thrown upwardly and outwardly from thevanes or scoops I04 in a helter-skelter deluge which flows over thesurface of the plates and dishes stacked in the basket and cleanses thesame. Some of the cleansing liquid, especially the larger dropletsthereof, bounce from the surface of one dish to another so that thosedish surfaces not in direct line with the spray from the impeller arewashed by secondar liquid streams received from other items beingwashed. There is, of course, some bouncing of the water or othercleansing liquid from the walls I2 of the tub onto the dishes and platescontained therein.

After the washing has been continued for a sufiicient length of time tocleanse the dishes, the valve 22 is opened and the cleansing fluiddrained out of the tub. Thereafter the washing water may be rinsed fromthe dishes by hot water introduced through a hand spray attached to thespigot 9 or directly from the spigot itself.

When used as a dishwasher the wringer is, of course, removed and storedelsewhere and the cover 84 is used to prevent loss of cleansing liquidfrom the interior of the tub. Should any of the dishes be extremelydifficult to cleanse or if it is desired to scour pots and pans in thesink I, a suitable flexible shaft is attached to the power take-oilshaft 68 and used to drive a rotary brush or bufiing wheel.
